re opening scene ocs file and materials indexs changing

[kurzwil20]

hi, I have been using the octane betas for a little bit and love the ease, speed and definetely quality it has offered me.
Recently with v5 beta I am having a problem where i load a obj mesh, assign materials, save the file and let it render. All is fine.

Client says they want to change some tone or color or strentgh of lights, so I go and open the same file I saved and where there used to be lets say 20 material nodes nor there is only 10. Just an example, not actual figure, but this is what has happened to me over the last week or so. I had not really noticed because I did not need to go back into my saved ocs files to make any lighting changes or such until today. Then i noticed it.

By the way I am not using any octane live nodes or saved nodes. All materials are built in the ocs file itself and ar every basic.
This kills any workflow gains of loading a mesh setting materials, lights, saving and thinking your good to go. Where I know have to either keep the said ocs scene file open until I know that all and any changes are truly done or just re open it and have to apply all materials again.. This really sucks.

Again I love the product, and do not recall having this issue with the previous betas, and no I am not changing my obj. mesh in the host 3d app, so that cant be the cause of it.

Just would like to know if anyone else has ran across this and knows of a fix.

Thanks all.

I encountered this trouble with the early demos of Octane, before 2.2, but the bug has been fixed for a while... very weird.

Same problem here! I saved the scene in v5 and reopened the .OCS file and the materials and light settings have gone!
I send also a notification about that problem but didnt get a relable answer...
I think is a major bug for now at this version.
Hope to see a fix in next release.

Got the same problem here

Guys do you just tweak the material settings in Node inspector, or do you create material nodes (or macros) and tweak those? Cause I always do the latest, and I haven't had this problems. Of course this problem had to be looked into, but as a temporary workaround you could try to create material nodes.

I always create the material nodes/macros, but sometimes when for example I hide one element in the scene and rewrite the .obj I find the materials shifted in position when I open the .ocs file. This will not occur if I have the .ocs file already open in Octane and I just reload the .obj
